To all whom t may Gomera:

Be it known that I, KURT M. Gnisnnn, a citizen of the lUnited States, residing at Hackensack, inf the county/.of Bergen and State of New Jersey, have invented certain new and useful Improvements in an Electrical Engine, of which the following is a speciiication.

My invention relates to an electrical engine, of the reciprocatory type, embodying a plurality of piston-cores.v f

An important object of the invention is to provide an engine of the above mentioned character, which when cranked or started, automatically makes and breaks the several circuits for the solenoid windings.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a central vertical longitudinal section, of an engine embodying my invention Figure 2 is a transverse section taken on line 2-2 of Figure 1,

Figure 3 is a detail section through one of the spring thrust contacts.

In the drawings, the numeral 5 designates preferably vertically arranged cylinders, carried by a crank-case 6. This crank-case hasY be-arings 7, receiving crank shaft 8, having .pairs of lcranks 9, 9' and 10, 10', as shown. Mounted to reciprocate within the cylinders are pairs of piston-cores 12, 12' and 13, 13',

connected with connecting rods 14, pivoted 'to the cranks.

Surrounding the c linders containing the pistons 12, 12' are so enoid windings 15 and 15, while solenoid windings 16 and 16', surround the other cylinders.

The wire 17 may be connected with the positive pole of a source of current, and wire 18 with the opposite pole. vThe wire 18 has connection with wires 19 and 20, connected with solenoid windings 15 and 16, and also has connection with wires 21 and 22, connected with solenoid windings 15' and 16'.

An'insulating strip 23 is arranged upon the top of the cylinders and secured thereto. Casings or tubes 24 extend through openings in this strip, there being a pair of tubes for each cylinder. Reciprocatory contacts 25, slide in the tubes 24, and are moved downwardly by springs 26. Thedownward move-ment of the contact is limited by a transverse pin 27, carried thereby, operating in slots 28.

The wire 17 has electrical connection with wires 29 and 29', connected with the outer contacts 25 of the cylinders within the windings 15 and 16. The wire 17 also has electrical connection with wires 30 and 35, electrically. connected with the contacts 25 of the cylinders within the solenoid windings 15 and 16. The contact 25 of the cylinder within the winding 15 is connected with a wire 31, connected with one end of the winding 15'. The contact 25 of the cylinder within the winding 15 is connected with a wire 32, connected Vwith one end of the winding 15.. The contact 25 within the cylinder of winding 16 is connected with wire 33, connected with one end of the winding 16. One

en d of the winding 16 is connected with wire 34, connected with the contact 25 in cylinder 5 of'winding 16. f

The operation of the pair of piston-cores 12 and 12 is`as follows:

When the crank-shaft 8 `is turned or cranked in starting the engine, the piston core 12' will be elevated, as shown in Figure 1, and engage contacts 25, closing a circuit to energize solenoid winding 15. In this closed circuit current will iiow' from wire 17, through wire 30, one contact 25, contact strip 25', the other contact 25, wire 32, solenoid winding 15, and through wire 19 to the wire 18. The winding 15 now becomes energized, and will draw the pistoncore 12 upwardly therein, the winding 15 being deenergized when the piston-core 12 descends suiiciently to break contact with wire 18. The operation of the circuits for the windings 16" and 16 are identical andit is thought unnecessary to describe the same.

It is to be understood that the form of my invention lherewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be remy. invention, I

i each solenoid winding and embodying afpir shaft, a, circuit connected with of 'contacts arranged at the upper end o the cylinder of the other piston-corefto be, engaged thereby, and a contact strip carried 15 by each piston-core.

In testimony whereof, I have affixedV my signature in the presence of two witnesses.
